When the 150-lb skier is at point A he has a speed of 5 ft/s. When the skier reaches point B on the smooth slope, the slope follows the cosine curve shown in (Figure 1). Suppose that y(x)=75cos(π/100x). Neglect friction and air resistance. Part A: Determine the skier's speed when he reaches point B on the smooth slope. Express your answer in feet per second to three significant figures
